<h4>● Overview</h4>
This effect generates motion blur.<br>
If you specify "Time during which the shutter is open before and after the current frame",<br>
the image will be blurred according to the object's path.<br>
As with iwa_BokehFx, the RGB values are converted into an exposure value before blurring,<br>
Therefore, even if the highlight part is blurred, the brightness is not impaired.

<h4>● Input Port</h4>
<UL>
<LI><b>Source</b> : Connect the input image.</LI>

<h4>● Parameters</h4>
<img src = ".\img\motionblur.png">
<UL>
<LI><b>Reference Object, Index</b> : Specify the object to follow the movement.<br>
When "Own Motion" is specified, the column movement of the input image is tracked.</LI>
<LI><b>Shutter Start</b> : Specify how long before the current frame the shutter should be opened.<br>
The unit is in frames. The higher the value, the bigger the blur.</LI>
<LI><b>Start Value</b> : Specify the strength of the blur when the shutter is opened.</LI>
<LI><b>Start Curve</b> : Specify how to apply the blur, from the time the shutter is opened up to<br>
the current frame. The default value is 1, with it the blur changes linearly.</LI>
<LI><b>Shutter End</b> : Specify how long after the current frame the shutter should be closed.<br>
The unit is in frames. The higher the value, the bigger the blur.</LI>
<LI><b>End Value</b> : Specify the strength of the blur when the shutter is closed.</LI>
<LI><b>End Curve</b> : Specify how to apply the blur, from the current frame up to the time<br>
the shutter is closed. The default value is 1, with it the blur changes linearly.</LI>
<LI><b>Trace Resolution</b> : Defines how detailed will be the tracking of the object's trajectory,<br>
while the shutter is open.<br>
At 1, the blur trajectory will be a straight line, even if the object is moving along a curve.</LI>
<LI><b>Hardness</b> : Gamma value of the film. It is used to convert the RGB values and exposure<br>
amount. The higher the value, the brighter the effect.</LI>
<LI><b>Afterimage Mode</b> : When active, instead of a smooth blur, an afterimage is drawn at the<br>
position traced, using the detail set with the "Trace Resolution" parameter.</LI>
